How to Grow Microgreens in Small Spaces: Apartment-Friendly Greens in About a Week

If you live in an apartment, condo, RV, dorm, boat, or small kitchen, traditional gardening can feel out of reach. You may not have a yard, a sunny patio, or room for large containers. That is exactly where microgreens shine. They are young edible greens that can grow in shallow trays and bring fresh flavor to sandwiches, bowls, smoothies, soups, and salads without requiring a garden bed.

Connor Hiebel’s video makes one simple point: small-space growing is not a compromise. It can be a practical way to bring fresh food closer to your daily routine. The key is to keep the promise realistic. Microgreens can be fast, compact, and beginner-friendly, but results still depend on seed choice, light, airflow, temperature, and watering habits.

Why Microgreens Work in Small Spaces

Microgreens are different from full-size garden vegetables. USDA Agricultural Research Service describes them as edible greens grown from vegetable and herb seeds and harvested without roots at the seedling stage, when the plants have two fully expanded seed leaves.³ That young harvest window is why they can fit into places where tomatoes, cucumbers, or traditional lettuce beds would not.

South Dakota State University Extension states that microgreens can add nutritious, fresh vegetables to the diet without taking up a lot of space in the home, and that they can be grown on a sunny windowsill or with supplemental lights in ordinary flowerpots or shallow trays.² Purdue Extension similarly describes microgreens as fresh greens that can be grown indoors year-round and used anywhere fresh herbs or vegetables would be used.¹

The practical lesson is simple: the grow space does not need to look like a farm. A clean corner of a counter, a shelf near a window, or a small grow-light station can become enough space for a tray.

How Much Space Do You Actually Need?

In the video, Connor explains that a tray can fit into the footprint of a small baking sheet or a sheet of paper. That is the right way to think about small-space microgreens: not in acres, not in raised beds, but in trays. Clemson Extension recommends clean shallow containers with drainage holes, 1 to 2 inches of moist potting soil, and either a sunny windowsill or adjustable grow light.⁵

This makes microgreens especially useful for renters and busy families. The tray can sit where you will remember it, which is often more important than having a perfect gardening setup. You see it, water it, rotate it, and harvest it as part of the kitchen routine.

Small-space location	Why it can work	What to watch
Kitchen counter	Easy to monitor and harvest for meals	Use a tray without leaks and keep away from raw meat prep.
Sunny windowsill	Natural light can support growth in many homes	Rotate if seedlings lean and avoid harsh heat through glass.
Small shelf	Uses vertical space instead of counter space	Add supplemental light if the shelf is dim.
RV, boat, or dorm	A compact tray can be moved as needed	Secure the tray, avoid overwatering, and maintain airflow.

The Apartment-Friendly Setup

You can keep the first setup intentionally simple. Purdue Extension recommends a matched pair of trays, with one tray that has drainage holes and one without drainage holes, along with a growing medium such as sterilized potting soil, coco peat, or mats, a spray bottle for initial watering, water for later bottom watering, and clean scissors or a sharp knife for harvest.¹ SDSU Extension also recommends untreated seed because seed treatments such as dyes, fungicides, or insecticides should not be consumed on young shoots.²

For small spaces, the two-tray system is especially helpful. The upper tray drains, the lower tray catches water, and you can bottom-water without splashing soil across the counter. That matters when your growing area is also your cooking area.

A Simple Seven-Day-Style Growing Flow

Connor’s video teaches a simple rhythm: keep the seeded tray dark for the first few days, then move it into ambient light, water daily, and rotate if the greens lean. That is a useful beginner framework, but the final timing should stay flexible. Purdue Extension says microgreens can yield fresh greens in 7 to 21 days, while SDSU notes that they are usually grown for a short time before harvest, commonly about three weeks.^{1 2}

A practical small-space workflow looks like this. In the first few days, focus on even moisture and germination. Once seedlings are up, move them into the best available light. In the final stretch, keep the tray evenly moist, improve airflow when possible, and harvest when the crop reaches the right stage for that variety.

Stage	What to do	Why it matters
Days 1–3, roughly	Keep seeds evenly moist and covered according to the crop.	Stable moisture supports germination without needing much space.
After germination	Move the tray to a bright windowsill or supplemental light.	Light helps seedlings green up and grow upright.
Growth phase	Check moisture daily and bottom-water when roots are established.	Consistent moisture is easier than rescue-watering a dried tray.
Harvest window	Cut cleanly above the soil line when the crop is ready.	Clean harvest protects quality and reduces mess.

This structure preserves the helpful “about a week” beginner message without pretending every crop or home environment behaves the same way.

The Tray Rotation Tip for Even Growth

One of the best small-space tips from the video is to rotate the tray when greens start leaning toward the light. Seedlings naturally grow toward the strongest light source. In a windowsill setup, one side of the tray may receive more light than the other, especially in apartments with one-directional exposure.

Rotation is not a magic yield multiplier. It is a practical canopy-management habit. Turning the tray helps more seedlings receive similar light over time, which can make growth look more even and easier to harvest. Purdue Extension’s guidance supports cautious light language because supplemental lighting may only be needed when minimum bright-medium sunlight is not available, and conditions vary by home.¹

Watering in Tight Spaces Without Making a Mess

Watering is where many small-space growers either succeed or struggle. The draft and video recommend lifting the top tray and adding water to the lower tray. That bottom-watering approach is useful because it lets the growing medium absorb moisture from below and keeps the leaves drier than constant overhead spraying.

SDSU Extension recommends gentle watering or bottom soaking so seeds are not washed to one side of the tray, while Clemson Extension recommends keeping microgreens moist and checking daily so they do not dry out.^{2 5} In a small kitchen, this means checking the tray once a day, watering only as needed, and avoiding standing water that can create odor, mold pressure, or countertop mess.

The best routine is visual and tactile. If the tray feels light and the growing medium is drying, water carefully. If the tray is heavy, soggy, or smells off, improve drainage and airflow before adding more water.

Harvest, Storage, and Food Safety

Most microgreens are harvested above the growing medium. Purdue advises cutting stems about one-quarter inch above the soil line or growing medium using scissors or a sharp knife, and notes that most crops, except pea shoots and some grasses, are harvested when they are 2 to 4 inches tall and true leaves are just emerging.¹ Clemson similarly recommends snipping above the soil with clean, sharp scissors and storing in the refrigerator until ready to eat.⁵

Because microgreens are often eaten raw, food safety belongs in a small-space article. FDA recommends washing hands for at least 20 seconds before and after preparing produce, washing produce under running water before eating, drying produce with a clean towel or paper towel, keeping raw produce separate from raw meat, poultry, and seafood, and storing perishable fresh produce in a clean refrigerator at 40°F or below.⁴

Purdue also emphasizes that clean and sanitized supplies are key for avoiding contamination from mold and pathogens, and it cautions against using garden soil indoors unless it has been sterilized first.¹ In a small home, this is even more important because growing, cooking, and storage may happen within a few feet of each other.

Best Beginner Crops for Small Spaces

Start with crops that fit your taste and your patience level. SDSU lists many possible microgreen crops, including arugula, basil, beans, beets, broccoli, cabbage, cilantro, kale, mustard, peas, and radish.² Clemson lists examples such as peas, broccoli, kale, radish, sunflowers, basil, and popcorn, and notes that seed companies often sell prepackaged microgreen mixes by flavor profile.⁵

For a first tray, choose one crop rather than mixing everything together. Radish and broccoli are often satisfying because they germinate quickly and bring strong flavor. Peas can be great for people who like crunch and sweetness, though larger seeds may need soaking and more space. Mustard can bring heat, while kale tends to feel familiar for everyday meals.

Crop idea	Flavor direction	Small-space note
Broccoli	Mild, green, versatile	Good everyday starter crop.
Radish	Peppery and bright	Great for sandwiches, tacos, and bowls.
Pea shoots	Sweet and crisp	Larger seeds may need soaking and more tray space.
Mustard	Spicy and bold	Use lightly if you prefer mild greens.

USDA ARS has reported that microgreens vary widely in vitamins and carotenoids by crop, but across 25 tested varieties they averaged about five times greater vitamin levels than mature counterparts.³ That supports describing microgreens as nutrient-dense, while avoiding unsupported claims that every tray has the same nutrient profile.
